Solvent extraction of copper from acidic sulphate solutions was carried out using the new oxime extractant, MOC 45 diluted in distilled kerosene. Increase of aqueous phase pH and extractant concentration in the organic phase increases the percentage extraction of metal. Increase of temperature during extraction resulted in an increase in percentage extraction whereas the reverse was observed during stripping. The process was tested for the recovery of copper from converter slag leach solution. The extraction and stripping efficiencies were > 98% and 100%, respectively. (C) 2000 Elsevier Science B.V.
